Kingtut, we had a run in with horsey people riding the trail in 50 Acre Wood. When I pointed out to her that she was riding the wrong (or "opposite-to-marked" if you're an anarchist type) way round an MTB trail, and the bottom half of said trail was blocked by forestry work, she got a bit arsey and claimed that she didn;t need to pay any attention to that sort of thing because she live there. My response of "Here? In the woods?" didn't go down too well.
Normally I feel like a dick telling people to get off the mountain bike trails, but she was properly clueless – not to mention leading a young girl around on a horse that was only just broken in.
Edit: sorry, thought that said Saturday morning. Saturday evening, erm, we were accoste by a bloke who seemd to have confused an admittedly well-attended night ride with the sort of gathering attended by young people with glow sticks, white gloves, whistles and jars of Vicks. 🙂
